The MetadataElement Class
Defined in: Keyview_Metadata.hpp
The MetadataElement
class is the type returned by Document::metadata or Subfile::metadata to represent a single metadata item. The MetadataElement
class has methods to inspect the name or type of the item, provide conversion to string for ease of transition from metadata_map
, and to provide access to the item in its original type (by using a Visitor Pattern implementation).
